0-A000067 Arduino Mega 2560 Rev3 <p><font color="00ff66" size="2" face="Arial, Helvetica, sans-serif">The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. </font></p>
<p><font color="00ff66" size="2" face="Arial, Helvetica, sans-serif">It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Mega is compatible with most shields designed for the Arduino Uno, Duemilanove or Diecimila.</font></p>
